assuming the fireplace isn't lit, open the nearest door and grab a towel and VERY GENTLY (i mean like handling a child) scoop up the bird and place it outside in an area where it can safely pull itself back together. keep an eye on it especially if you live near cats because they will try to eat it. if the bird struggles when you try to pick it up, just keep trying nut make sure you are very gentle. hope this helps!
